"The most important thing today is that the cameraman who got struck by the tire does not appear to have suffered any life-threatening injuries," Horner told the sport's official website.

"It's a timely reminder that working in the pit lane is dangerous. Everyone reacted incredibly quickly and the most important thing is to hear that he seems to be fundamentally OK.

"We need to understand what went wrong in that first pit stop for Mark, but as I said, our main concern today is knowing that the cameraman is OK."
